The volume of a complete sphere is [ 4/3 pi R3 ]. The volume of a hemisphere is 1/2 of that ... pretty close to [ 2/3 pi R3 ].
(1/2) divided by (3/4) = 2/3 or 0.6666667
Volume of cone = 1/3*pi*r2*h Volume = 1/3(pi)(12)2(27) = 4072 cubic units =============
Volume = Height * Area of Circle Area of Circle = pi*(Diameter/2)^2 Height = Diameter Volume = Diameter*(pi*(Diameter/2)^2) Volume = (pi/4)*Diameter^3 Diameter = (4/pi) * Volume ^ (1/3) Diameter = (4/3.14)*220^(1/3) ≈ 6.54 cm
5xcube root of 2 or 5x(2^(1/3) which is about 6.29961 Or The volume of a cube, V, is: V = a^3 (side^3), we have: 250 = a^3 or a^3 = 250 a =(250)^(1/3) (you can do this in your calculator) a ≈ 6.29961
